Nov 24, 2016 · Boiler Efficiency:-Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilized to generate steam. There are two methods of assessing boiler efficiency. 1) Boiler Efficiency by Direct Method: Where the energy gain of the working fluid (water and steam) is compared with the energy content of the boiler fuel.

Clean boiler heat exchange surfaces allow for maximum heat transfer from the burning fuel to the boiler water. Feedwater quality is critical to prevent deposit formation within the boiler and maintain peak efficiency. Water-side deposits will insulate heat exchange surfaces and sharply increase fuel consumption.

Shifting to real time efficiency monitoring can improve the boiler efficiency significantly depending upon the boiler type and actual conditions at site. In nutshell, monitoring and maintaining the boiler efficiency for the overall operational life of the boiler is a must to cut fuel bills and reduce carbon footprint.

Boiler efficiency (%) = 100 (percentage of flue-gas losses + radiation and other unaccounted losses). Steam and high temperature hot water boilers 7 Types of fuel used in boilers There are a wide range of fuels used. Boilers commonly burn standard hydrocarbon fuels, such as natural gas, oil and coal, but some burn tallow or waste materials.

Blowdown for steam boilers o Check the normal operating water level (NOWL) in the boiler. If the Low Water Cut-Out (LWCO) is mechanical (a float), it must be blown down (drained) on a regular basis to prevent sediment from accumulating in the float chamber. o Improve water treatment to minimize boiler blowdown.

Steam boiler has some technical terms that be generally used. One of them is MAWP (Maximum Allowable Working Pressure) which means that all of working pressure at the pressure part shall not exceed MAWP. MAWP on the header or drum can be calculated based on the equation below: MAWP = (t x E x TS) / (R x SF)

Improving Boiler Efficiency. Your boiler probably accounts for the majority, if not all, of your heating fuel bill. If you tend to budget a fixed dollar amount for this fuel bill, you may be interested in knowing that most boiler systems are, at best, 85% efficient with an average efficiency of only 65% to 75%.

1. Reheating cycle of steam turbine. In this system,the steam's ability to work may be slightly increased by reheating the steam during its passing through the turbine.Steam first enters into the turbine at superheated state.Now steam's pressure and temperature is improved by efficiency of Rankine cycle.This will increase its expansion ratio and steam has become wet condition at the end of
